ROBERT M. WADE, OF WADESVILLE, VIRGINIA.

LUBRICATOR.

Specification of Letters Patent No. 11,024, dated .T une 6, 1854.

To all/whom t may concern Be it known that I, ROBERT M. WADE, of Wadesville, in the county of Clarke and State of Virginia, have invented a new and useful Improvement in OilfCups for Locomotive and other Steam Engines; and I do hereby declare that the following is a full, clear, and eXact description of the construct-ion and operation of the same, lreference being had to the annexed drawin forming part of this specification, in whic i- Figure 1 is a front elevation of the oil cup. Fig. 2 is a side elevation of the same. Fig. 3 is a section on line a: of Fig. 2 and perpendicular to the axis of the plug.

Similar characters of reference denote the same part. A

The object of my invention is to so ar range the several parts of the lubricator that the engineer may supply and discharge the feed cylinder by means of a rod leading from the arm of said cylinder to a position within his reach.

The invention consists in constructing in the feed cylinder two separate openings, one for'feeding and the other for discharging; the relative position of these openings being such that when one is performing its functions the communication between the other and its corresponding passage will be cut oif, either opening being brought into operation by the movement of the cylinder, arm within certain limits, produced by a rod connected With said arm and leading to a position near the engineers stand, so that the oil may be admitted to the steam cylinder at all times without the necessity of the engineer leaving his stand.

To enable others skilled in the art to make and use my invention I will proceed to den scribe its construction and operation.

In the drawing A is a hollow cylindrical `chamber to cont-ain the oil or other lubricant. The outer surface of this cylinder is ground so as to closely fit the cylinder or jacket B, and be capable of turning within and in close contact with the same. Leading from the cylinder B are the branches C, D,

the delivery of the same through the passage d. The openings are so situated as shown in Fig. 3 that when one a is in communication with the channel e the other will' be closed by the inner surface of the jacket B, and all communication with the steam cylinder cut off, while if the opening t commu# nicate with the channel d and the oil flow to the steam cylinder the outer surface of the plug A will close the channel c and all communication between the reservoir E and the chamber A will be cutoi Attached to the outer face or projecting portion of the plug A is the arm F for turning said plug, the amplitude of the movements being governed by the studs P P", be-` tween which th`e arm is at liberty to oscillate, the studs being so placed that when the lever F is in contact with either stud one of the openings a Z will perform its functions. From the extremity of the lever F a rod R is carried to a position within reach of the engineer, so as to place the movement of said lever at all times under his control, without the necessity of his leaving his stand. This effective action of the apparatus by the slight movement of the lever F is due to the construction of the cylinder A with the two openings a and b, relatively situated as herein described, for with but one aperture, as these cups are generally constructed, it would be impossible to operate them with a rod, as the operating position of the opening at both feed and discharge, would necessarily be a dead point of the crank and rod, making the rotation of the cylinder A by power' applied to the rod an impossibility.

What I claim as my invention and desire to secure by Letters Patent, is-

The hollow cylinder A in combination with the acket B, constructed and operated as herein before set forth, namely, the two apertures in the cylinder being so situated that while the upper one is admitting oil into the cylinder, the lower one is closed to the steam, and when the lower aperture is open to the steam, the upper one is closed to the steam and to oil in the cup.

In testimony whereof, I have hereunto signed my name before two subscribing witnesses.
